Compress PDF to 500 KB

Frequently asked questions
How do I compress a PDF to 500 KB?
Upload it above and select “Compress to under 500 KB”. The tool keeps the lightest compression that brings the file under 500 KB and shows the before and after sizes.
Will the text stay selectable?
Pages that contain only text are copied into the new file unchanged, so their text stays sharp and selectable. Pages with photos or scans are re-compressed as images, so text on those pages becomes part of the image.
Why can my PDF not reach 500 KB?
Text, fonts and vector graphics are kept as they are, so if they alone take up more than 500 KB, compressing the images cannot bring the file under it. Splitting the PDF into smaller parts with Split PDF usually helps.
Is my PDF uploaded?
No. The PDF is compressed in your browser and never leaves your device.
